Bel Air 770 / Sewmor 770 cam issues
Hello, I recently bought this beautiful machine for $17 and when I got it home I ran it through the gambit. The wheel turned, there was no creaking when it moved, the needle didn't hit the foot, and when plugged in the motor was free and just had a bit of dust in it. When I loaded it up with new thread and a fresh bobbin it straight stitched fine and would do a basic zig zag fine, the issue came in when I tried to use it's other functions (part of the reason why I got it). When I turned the dial on the machine away from straight stitch it has tough to move and than the machine just froze up. When I took off the top I saw a resin Cam and the Cam follower. It looks like as the machine sews the cam follower goes along the cam from right to left and than back, but when I took the top off the follower was stabbing into the resin. I backed the follower off and have been looking for information about the cam or the follower or really even the machine ever since. I'll try and post pictures but I haven't seen anything like it before and I don't really know what to search online to find out more. Any ideas or information would really help.

I see a lot of old oil in there. You will have lots of cleaning, new Tri-flow and patience - some little part whether a gear or a spring or what ever is gummed up. There are some machines I never know what I do to make one work just clean and oil until they work. If someone messed with it it might be more of a problem. I'm thinking Belaire was made by Brother. The Belaire machines I've seen have been nice machines. It is possible that since the part has been removed that something is out of timing.

I have almost this same machine. Mine has metal cams in it, and it almost looks like the cams have been removed from that resin spool. I'm wondering if someone harvested the cams from your machine. At least it looks that way to me. And since the cams are missing, that would be why the follower is digging into it:<

So what would my options be then? I mean it does a decent straight stitch and zig zag. I'll keep cleaning it and see if I can get most of the old oil and gunk out of it but I think your right about the missing metal for the cams. That's a little disappointing. Would you have any ideas on where I would even search for a new cam for this machine?
